Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 75 guests × 75% drinking rate | 56 drinkers |
| Calculate base consumption | 56 drinkers × 1.5 drinks/hour × 4 hours | 336 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 273 adjusted drinks |
| Apply Halloween party modifier | × 0.9 (-10% for wine) | 247 wine servings if served alone |
| Share of the bar | 247 servings × 17.4% | 43 wine servings |
| Convert to bottles | 43 servings ÷ 5 servings per bottle | 8.6 bottles (raw) |
| Add 15% buffer & round up | 8.6 × 1.15 = 9.9, rounded up | 10 bottles |
The Knot's wedding guide plans one drink per guest per hour with a 50/25/25 liquor, beer and wine split. This model counts only the guests who drink, slows the pace after the first hour, and keeps a 15 percent margin; read the methodology.

Wine at a Halloween party
How much wine do I need for 75 guests?
You need 10 bottles of wine for 75 guests at a Halloween party, assuming you are serving a full bar. That is 43 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 57 bottles instead.
How much wine per person for a Halloween party?
Plan for 0.6 servings of wine per person at a Halloween party with a full bar. This accounts for the fact that not everyone drinks alcohol, that consumption slows as the event progresses, and that wine is only 17.4 percent of what gets poured.
How many servings are in a bottle of wine?
One bottle of wine contains 5 servings. For 75 guests, you'll need 10 bottles to provide 43 total servings.
What percentage of the bar is wine at a Halloween party?
About 17.4 percent of the drinks poured at a Halloween party are wine. With 75 guests, roughly 56 will be drinking, and that share works out to 10 bottles.
Should I buy extra wine as a buffer?
Our figure of 10 bottles already includes a 15% buffer (1 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 10 bottles of wine last for 75 guests?
10 bottles of wine will last approximately 4 hours for 75 guests at a Halloween party, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
